물품으로서, 조성물의 중량을 기준으로 중량 퍼센트로, (A) (1) 34% 내지 55%, 또는 65% 내지 80%의 실온에서의 결정도 및 (2) 0.1 내지 50 dg/min(분 당 데시그램)의 용융지수(I)를 갖는, 2 내지 80 중량 퍼센트(중량%) 미만의, 에틸렌계 중합체; (B) 3 내지 30 중량%의 할로겐화 난연제; (C) 3 내지 30 중량%의 무기 안티몬 난연제; 및 (D) 0 내지 10 중량%의, 상기 무기 안티몬 난연제 이외의 무기 난연제 중 적어도 하나, 예를 들어, 산화 아연을 포함하는, 수분-가교성, 중합체성 조성물로 제조된 물품은, 실온에서의 결정도 요건을 갖지 않는 에틸렌계 중합체를 포함하는 조성물로 제조된다는 점을 제외하면 모든 면에서 동일한 물품에 비해 향상된 ACBD 특성을 나타낸다. The invention relates to a moisture-crosslinkable, polymeric composition comprising in weight percent based on the weight of the composition:(A) 30 to 79 wt% of an ethylenic polymer of any crystallinity at room temperature;(B) 2 to less than (<) 27 wt% of an ethylenic polymer (1) other than the ethylenic polymer of (A) in the moisture-crosslinkable, polymeric composition, and (2) with (a) a crystallinity at room temperature of 34% to 55%, or 65% to 80%, and (b) an I2 of 0.1 to 50 dg/min;(C) 3 to 30 wt% of a halogenated flame retardant;(D) 3 to 30 wt% an inorganic flame retardant;(E) 0.3 to 5 wt% of a graftable silane-containing compound;(F) 0.01 to 20 wt% of a silanol condensation catalyst;(G) 0.02 to 0.1 wt% peroxide initiator; and(H) 0 to 10 wt% of at least one inorganic flame retardant other than the antimony flame retardant.
